System for detecting an accident

Abstract

A system integrated in a helmet or another headgear, for the registration of direct violence against the head / body that a wearer of the helmet is subjected to in connection with an accident, comprising at least one sensor (12) intended to detect movements, at least one sensor for measuring vital data, a unit (13) arranged to register and receive data from the sensor and calculate at least one parameter of the head movement, based on said calculations, the unit being arranged to identify when an accident has occurred and to store data a certain time before the accident and stop storing a certain time after the accident as well as to generate an alarm and transmit information related to the accident to a receiver. Furthermore, the system is arranged to recreate the course of events based on registered, stored and processed data in order to provide as correct a picture of the accident as possible, and to monitor how vital data are developing after the accident so that the ill-fated thereby should get as quick and correct care as possible.

Description

TECHNICAL FIELD[0001]The present invention relates to a system for the detection body movements which indicate direct violence to the head and / or body of a person / individual in connection with an accident and change of vital data due to an accident, and more precisely to a system according to the preamble of claim 1.[0002]By detecting the direct violence that arises in connection with an accident, information for automatic calling for nursing staff for an emergency medical effort can be generated when an accident has occurred, and thereby make the medical effort as quick, good and cost-effective as possible. By detecting change of vital data, the medical effort can be further improved qualitatively.[0003]Particularly, the invention relates to fields of application where a helmet of some type is used, alternatively activities where violence against the body is usually occurring, for instance, during motorcycle-driving, cycling, skiing, riding, skydiving, mountain climbing, car-drivin...

AI Technical Summary

Benefits of technology

[0042]The invention also relates to a device for the registration, storage, processing and transfer of information about direct violence against a body so that the medical effort becomes as quick, good and cost-effective as possible.

Problems solved by technology

In accidents, the motorcycle driver often becomes so badly injured that he / she himself / herself cannot describe what has happened, much less to contact the emergency service centre.

In addition, 45% of all fatal motorcycle accidents are so-called single-vehicle accidents, which may mean that there are no witnesses of the accident.

In addition, problems may arise in the communication chain within and between the different involved medical teams, which may result in vital information being misunderstood, misrepresented or omitted.

The disadvantage, and what separates this system from the present idea, isthat it is limited to team sports,that it monitors physiological parameters of external parts of the body in order to, when a predefined amount of accumulated violence is attained, notify, for instance, a coach who takes the player off the plane to counteract more extensive injury,that it does not link registered parameters to body movements, and therefore it cannot be used to recreate a course of events.

The disadvantage, and what separates the system from the present idea, isthat the system depends on a plurality of sensors,that it requires that the sensors are placed with at least one axis perpendicularly to the head,that it preferably is designed to alarm when a predetermined amount of accumulated violence against the body has been attained,that it preferably is used to register preknown violence against the body, which thereby means normal and expected violence,that it is not related to calling about accidents, which applies to abnormal and non-expected violence.

The disadvantage, and what separates the system from the present idea, isthat it only processes pulse, blood pressure and oxygen absorption capacity relating to the injured person,that it does not process violence against specific external parts of the body (the head),that it uses the accelerometer only to register that the accident occurs,that it not registers course of events over time, and thereby cannot be used to recreate and visualize course of events, andthat it is limited to send the information by means of a telephone.

The disadvantage, and what separates the system from the present idea, isthat it is connected to the car and thereby not registers violence against the body, andthat it only processes static (preprogrammed) data.

The disadvantage, and what separates the system from the present idea, isthat it is connected to the car and thereby only indirectly applies to violence against the body,that it employs cameras and microphones to collect data,that it seems to have, as a primary function, to predict accidents by means of the above-mentioned data collection.

However, this system is not arranged to register how vital data are developing after the accident has occurred.
